A pressure cooker saves both time and fuel in cooking because inside the cooker, the
boiling point of water is raised
pressure is constant
heat is completely trapped
temperature is evenly distributed
volume of steam varies
Correct answer is A
When atmospheric pressure increases, the boiling point becomes higher, and when atmospheric pressure decreases (as it does when elevation increases), the boiling point becomes lower.
